Available
Mackay M139 is the larger of the two heavy duty flange isolators: a base 157mm long, a body 102mm wide and a height of 48mm, weighing 0.6kg. The telescopic metal inserts provide considerable stability in all directions; loads can be suspended as well as supported, and interlocking flanges ensure suspension even if the rubber is completely destroyed by fire, etc..
Available as four part numbers, M13940, M13950, M13960 and M13970, in Duro 40, 50, 60 and 70. The base is bolted down through two 14.2mm holes, 127.0mm apart. A stainless steel version is available separately as M13960SS.

Choosing the right option
Choose by load first. Each part number has its own compression load range and its own Duro, so work out the share of the machine weight each isolator will carry and pick the range that contains it. Then check the base against your steelwork: two 14.2mm holes, 127.0mm apart, 157mm overall length. All properties are nominal.
